Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a pole mounting bracket used for attaching an electrical equipment storage box or the like to a pole such as a utility pole.

(Prior Art) As shown in FIGS. 4 and 5, the conventional pole mounting bracket has a flange-groove rail-shaped object fixing bracket 51 with a T-shaped hook portion 53 formed at the tip. A pair of holding fittings 52 are engaged with each other, and an object fixing fitting 51 is attached and fixed to an object 54 such as an electrical equipment storage box, and the holding fitting 52 is held by a ball 55. , insert the bolt 57 into the bolt insertion hole 56 provided in the tightening piece 52a, and tighten the nut 5.
By tightening and fixing the object 54 with the
was to be attached to pole 55.

(Problem to be solved by the invention) However, in such a conventional device, the position of the hook portion 53 of the holding fitting 52 is not fixed with respect to the attachment fitting 51, so the holding fitting 52
Not only is it troublesome to hold the object 54 on the pole 55, but if an impact is applied to the object 54 after installation, the position of the hook portion 53 will shift and the tightening of the holding fitting 52 to the pole 55 will loosen. There were various problems such as objects 54 falling.

(Means for Solving the Problems) The present invention was made to solve the above-mentioned problems, and includes a pole-holding device at the center of the upper and lower edges of the mounting plate that is perpendicular to the object to be mounted. A horizontal reinforcing plate with a cutout is installed, and a fitting for fixing the object to be attached has a T-shaped engagement hole in the connecting piece bent at the left and right edges, and a bolt at the base end. a pair of curved holding fittings each having a bent fastening piece with an insertion hole and a T-shaped hook portion formed at the tip that can be engaged with the engagement hole; It is characterized in that the front plate part or hook part of the part is inclined obliquely inward.

(Example) Next, an example of the present invention will be described in detail based on FIGS. 1, 2, and 3.

Reference numeral 1 denotes a fixture for fixing an object to be attached, which is attached to the back of an electrical equipment storage box, etc.;
is a connecting piece part in which horizontal reinforcing plate parts 3, 3 are stretched on the upper and lower edges of the vertical mounting plate part 2, and the front plate part 4b that continues beyond the vertical plate part 4a on the left and right edges is directed diagonally inward. 4, 4 are bent and formed. A forward plate portion 4b extending diagonally inward from the vertical plate portion 4a of the connecting piece portion 4
A T-shaped engagement hole 5 having a vertically elongated enlarged hole portion 5a is provided in the portion leading to .

6, 6 is a pair of holding fittings curved in an arc shape,
At the tip of each holding member 6, there is a T-shaped hook portion having a head portion 7a that can pass through the enlarged hole portion 5a and engage with the engagement hole 5, and a neck portion 7b that can slide inside the engagement hole 5. 7
is formed. In this embodiment, the front plate portions 4b of the connecting pieces 4, 4 of the attachment fixture 1 are inclined inward, but the connecting piece 4 is straight and the hook portion 7 of the holding bracket 6 is tilted inward. may be inclined obliquely inward.

In addition, 8, 8 is a tightening piece portion with a bolt insertion hole 9 bent at the base end of each holding fitting 6;
is a notch for holding a pole provided at the center of the reinforcing plate parts 3, 3. Reference numeral 11 denotes a through hole provided in the mounting plate 2, through which the object fixing fitting 1 is connected to the object 21.
This is for inserting bolts when attaching and fixing.

(Function) With this structure, the mounting plate portion 2 of the attachment fixture 1 can be attached to the back of the attachment object 21, such as an electrical equipment storage box, by means of bolts, nuts, welding, etc. Furthermore, the hook portions 7 at the tips of the holding fittings 6, 6 are engaged with the engagement holes 5, 5 of the connecting pieces 4, 4 bent on the left and right edges of the mounting plate portion 2, and then As shown in Figure 2, the arcuate curved portion is attached to the pole 22, and the tightening piece 8 bent at the base end of each holding fitting 6 is tightened with the bolt 23 and nut 24. The attachment of the object 21 to the pole 22 by fixing is similar to conventional pole attachment fittings of this type.

However, in the device according to the present invention, the T-shaped hook portion 7 provided at the tip of each holding fitting 6 connects to the T-shaped engagement hole 7 formed in the connecting piece portion 4 of the attachment fitting 1.
In addition, the front plate portion 4b of the connecting piece portion 4
Or, since the hook part 7 is inclined obliquely inward,
When the holding fitting 6 is tightened, the hook portion 7 naturally slides within the engagement hole 5 of the front plate portion 4b and comes into contact with the edge of the tip hole of the engagement hole 5, thereby fixing the position, and the installation work to the pole is completed. This can be done extremely easily.

In addition, since the notch 10 provided at the center of the horizontal reinforcing plate parts 3, 3 stretched over the upper and lower edges of the mounting plate part 2 is fitted to the pole 22, the installation is excellent in terms of strength. Furthermore, even if an impact is applied to the object 21 after installation, the position of the hook portion 7 with respect to the object fixing bracket 1 will not shift, so the clamping of the holding bracket 6 against the pole 22 will loosen and the object will be damaged. There is no fear that 21 will fall.

Furthermore, in the present invention, since the proximal end portion of the engagement hole 5 is formed into the enlarged hole portion 5a, the holding fitting 6,
It is possible to attach the fixture 1 to the fixture 21 with the fixture 6 removed, making the installation work easy.In addition, the holding brackets 6, 6 can be easily attached to the fixture 1 when the fixture 6 is removed. Since it can be separated into two parts, it has the advantage of being able to be stored without taking up much space.

(Effects of the invention) As is clear from the above explanation, the invention has the following effects:
The position of the hook part of the holding bracket relative to the object fixing bracket is easily fixed, making it easy to attach to the pole, and even if an impact is applied to the object after installation, the holding fitting will loosen and prevent the object from being attached. There is no risk of objects falling. Therefore, the present invention eliminates the problems of conventional pole mounting brackets of this type and has extremely great practical value.
